Answer 2

Let's break this down step by step:

1. 7 days and 21 hours + 3 days and 14 hours = 11 days and 11 hours
2. 5 * 6 = 30 centimeters
3. 3 meters - 56 centimeters = 244 centimeters
4. 1 kilogram and 250 grams * 4 = 5 kilograms
5. 9 square decimeters = 0.81 square meters
6. 4 square centimeters = 0.0004 square meters, so 9 square decimeters - 4 square centimeters = 0.8096 square meters
7. -54 centimeters squared is not a valid calculation, as you cannot square a negative value.
8. 5 days divided by 10 = 0.5 days

So the final answer is 0.5 days.
